Description

Wireless communication method, terminal device and network device

technical field

The embodiments of the present application relate to the field of communication, and more particularly, to a wireless communication method, terminal device, and network device.

Background technique

Communication architectures such as Device to Device (D2D), Vehicle to Vehicle (V2V), and Vehicle to Everything (V2X) can be implemented based on Sidelink (SL) technology. The communication between them is different from the way in which the communication data is received or sent by the base station in the traditional cellular system. This direct communication method between terminals has higher spectral efficiency and lower transmission delay.

Two transmission modes are defined in the 3rd Generation Partnership Project (3GPP): the first mode and the second mode. The first mode: the transmission resources of the terminal are allocated by the network device; the second mode: the terminal selects a resource in the resource pool for data transmission. In New Radio (NR)-V2X, in order to improve reliability, sideline feedback is introduced. For example, for unicast transmission, the sender terminal sends sideline data to the receiver terminal, the receiver terminal sends sideline feedback information to the sender terminal, and the sender terminal determines whether retransmission is required according to the sideline feedback information of the receiver terminal . When the sideline transmission resource is scheduled by the network equipment, that is, the above-mentioned first mode, the sender terminal needs to report the sideline feedback information to the network device, and the network device decides whether to allocate retransmission to the terminal according to the sideline feedback information reported by the terminal. resource. Wherein, the transmitting end terminal can dynamically activate or deactivate the sideline feedback. However, in the first mode, the network device does not determine whether the sideline feedback is activated or deactivated by the sender terminal. Therefore, the network device does not consider whether the sideline feedback is activated when allocating transmission resources to the sender terminal. However, for the sender terminal and the receiver terminal, it takes time for them to detect the received data or prepare the data to be sent, which will lead to the unreasonable transmission resources allocated by the network equipment, resulting in the situation that the data cannot be transmitted. , thereby reducing the reliability of the communication system.

Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. With regard to the embodiments in the present application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Before introducing the technical solution of the present application, the relevant concepts of the present application are described below:

1. D2D/V2X

Device-to-device communication is a D2D-based sidelink transmission technology. It is different from the traditional cellular system in which communication data is received or sent through the base station. Therefore, it has higher spectral efficiency and lower transmission delay. The IoV system adopts terminal-to-terminal direct communication, and 3GPP defines two transmission modes: the first mode and the second mode.

The first mode: As shown in Figure 1, the transmission resources of the terminal are allocated by the network device, and the terminal sends data on the side link according to the resources allocated by the network device; the network device can allocate resources for a single transmission to the terminal. , the terminal can also be allocated semi-static transmission resources. Also known as Mode 3 in LTE-V2X.

Second mode: As shown in FIG. 2 , the terminal selects a resource in the resource pool for data transmission. Also known as Mode 4 in LTE-V2X.

2. NR-V2X

In NR-V2X, autonomous driving needs to be supported, so higher requirements are put forward for data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, More flexible resource allocation, etc.

In NR-V2X, unicast and multicast transmission methods are introduced. For unicast transmission, there is only one terminal at the receiving end. As shown in Figure 3, unicast transmission is performed between UE1 and UE2; for multicast transmission, the receiving end is all terminals in a communication group, or a certain transmission All terminals within the distance, as shown in Figure 4, UE1, UE2, UE3 and UE4 form a communication group, in which UE1 sends data, and other UEs in the group are receivers; for broadcast transmission, the receiver is the sender. For any terminal around the terminal, as shown in FIG. 5 , UE1 is the transmitting terminal, and other UEs around it, namely, UE2-UE6 are all receiving terminals.

3. Lateral feedback

In NR-V2X, in order to improve reliability, a sideline feedback channel is introduced. For example, for unicast transmission, the sender terminal sends sideline data to the receiver terminal, including the physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) and the physical sidelink Shared Channel (Physical Sidelink Shared Channel, PSSCH) on The receiving end terminal sends sideline feedback information to the transmitting end terminal, and the transmitting end terminal judges whether to perform retransmission according to the feedback information of the receiving end terminal. The sideline feedback information is also referred to as hybrid automatic repeat request (Hybrid Automatic Repeat Qequest, HARQ) feedback information. The sidelink feedback information is carried in a sidelink feedback channel, such as a physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH).

The sender terminal can dynamically activate or deactivate the sideline feedback through the sidelink control information (Sidelink Control Information, SCI). The detection result feeds back a positive acknowledgement (Acknowledgement, ACK) or a negative acknowledgement (Negative Acknowledgement, NACK) to the sender, and the sender terminal decides to send retransmission data or new data according to the feedback information from the receiver; if the sideline feedback is deactivated, then receive The end terminal does not need to send feedback information. The sender terminal usually sends data in a blind retransmission manner. For example, the sender terminal repeatedly sends each sideline data K times, instead of deciding whether to send retransmission according to the sideline feedback information. data. When the sideline transmission resources are scheduled by the network equipment, that is, the above-mentioned first mode, the sender terminal needs to report the sideline feedback information to the network equipment, and the network equipment decides whether to allocate retransmission resources to the terminal according to the ACK or NACK reported by the terminal.

Fourth, the resource definition of the transmission channel

In this application, PSSCH resources are referred to as sideline transmission resources. The resources of the PSFCH are called sideline feedback resources. The Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH) is used to transmit the sideline feedback information sent by the sender terminal to the receiver terminal. The resources of PUCCH or PUSCH are It is called uplink transmission resource.

FIG. 6 is a sequence diagram between transmission channels provided by an embodiment of the present application. As shown in FIG. 6 , the network device allocates resources of two PSSCH and one PUCCH at a time through downlink control information (Downlink Control Information, DCI). The receiving end terminal processes the PSSCH, and prepares the sideline feedback information to be transmitted through the PSFCH. The time is a, then the starting position of the first symbol of the PSFCH corresponding to the PSSCH is between the end position of the last time domain symbol occupied by the PSSCH. The time interval cannot be less than a, that is, the time interval must be greater than or equal to a, or the start position of the first symbol of the PSFCH corresponding to the PSSCH cannot be earlier than the end position of the last time domain symbol occupied by the PSSCH plus Time interval a; the sender terminal receives the PSFCH, if the PSFCH carries NACK, the sender terminal needs to prepare to retransmit the PSSCH, and the time interval between retransmitting the PSSCH and receiving and processing the PSFCH cannot be less than b, where b includes at least sending The terminal detects the PSFCH, prepares the time of the retransmitted PSSCH, and transmits and receives the conversion time, for example: as shown in Figure 6, the end position of the last time domain symbol occupied by the PSFCH is between the start position of the first symbol of the next PSSCH The time interval between the two must be greater than or equal to b, or, the start position of the first symbol used for the next PSSCH retransmission cannot be earlier than the end position of the last time domain symbol of the PSFCH corresponding to the previous PSSCH plus time Interval b, which is equal to b is given in the figure; the transmitting terminal receives the PSFCH and prepares to report the sideline feedback information to the network through the PUCCH (or PUSCH) The time interval is c, that is, the last time domain symbol occupied by the PSFCH The interval between the end position of the PUCCH and the start position of the first symbol of the PUCCH cannot be less than c, or the start position of the first symbol of the PUCCH cannot be earlier than the last occupied by the last PSFCH corresponding to the PSSCH allocated by the network. The time interval c is added to the end position of the time-domain symbol. Figure 6 shows the case where the interval between the end position of the last time-domain symbol occupied by the PSFCH and the start position of the first symbol of the PUCCH is equal to c. Therefore, in the second mode, that is, when the terminal equipment independently selects resources, when the sideline feedback is activated, when the terminal selects transmission resources, the minimum time interval between two adjacent PSSCHs should be Z=a+b , for example: as shown in FIG. 6 , the time interval between two adjacent PSSCHs is a+b.

When the sideline feedback is deactivated, that is, the receiver terminal is not required to perform the sideline feedback, and the sender terminal can use blind retransmission, and at this time, two adjacent PSSCH transmission resources can be adjacent time slots.

In the second mode, the terminal device can autonomously select resources, but as mentioned above, in the first mode, the network device does not determine whether the sender terminal has activated or deactivated the sideline feedback. When the terminal equipment allocates transmission resources, it does not consider whether the sideline feedback is activated. However, for the sender terminal and the receiver terminal, it takes processing time to detect the received data or prepare the data to be sent, which will cause the network The transmission resources allocated by the device may be unreasonable. For example, it is assumed that according to the transmission resources configured by the network device, the time interval of adjacent PSSCH resources configured by the network device is less than the above a+b, resulting in the situation that data cannot be transmitted, thereby reducing the reliability of the communication system.

In order to solve this technical problem, the present application determines whether to activate the sideline feedback according to the time interval between the transmission resources allocated by the network device. Alternatively, the terminal device may perform sideline transmission using part of the transmission resources allocated by the network, and activate the sideline feedback, or the terminal device may indicate to the network device whether to activate or deactivate the sideline feedback, so that the network device allocates transmission resources, Alternatively, the network device instructs the terminal device to activate or deactivate the sideline feedback. In this case, the network device can learn whether the sideline feedback is activated, and based on this, the transmission resources can be allocated.

It should be noted that, the terminal device referred to in the following embodiments is the terminal device of the transmitting end, which will not be repeated below.

Example 1

FIG. 7 is an interaction flowchart of a wireless communication method provided by an embodiment of the present application. As shown in FIG. 7 , the method includes:

Step S710: The network device sends configuration information to the terminal device, where the configuration information is used to configure multiple transmission resources for the terminal device.

Step S720: The terminal device determines whether to activate sideline feedback according to the time interval between multiple transmission resources.

Optionally, the configuration information is used to configure multiple sideline transmission resources for the terminal device.

Optionally, the configuration information is used to configure multiple sidelink transmission resources and one uplink transmission resource for the terminal device.

Optionally, the configuration information is used to configure one sideline transmission resource and one uplink transmission resource for the terminal device.

For the configuration information of the above-mentioned different functions, step S720 has different optional modes, but is not limited to this, and the details are as follows:

Option 1: The configuration information is used to configure multiple sideline transmission resources for the terminal device. If the time interval between at least one group of two adjacent sideline transmission resources in the multiple sideline transmission resources is less than the first threshold, the terminal device deactivates the sideline feedback.

Option 2: The configuration information is used to configure multiple sideline transmission resources for the terminal device. If there are at least one group of two adjacent sideline transmission resources in the multiple sideline transmission resources that satisfy the first condition, the terminal device deactivates the sideline feedback. Wherein, for any group of two adjacent sideline transmission resources in at least one group of two adjacent sideline transmission resources, the two adjacent sideline transmission resources satisfying the first condition include: two adjacent sideline transmission resources: The start position of the second sideline transmission resource in the line transmission resources is located before the end position of the sideline feedback resource corresponding to the first sideline transmission resource in the two adjacent sideline transmission resources plus the second threshold . It should be understood that the first sideline transmission resource is the sideline transmission resource whose time domain position is in the front of the two adjacent sideline transmission resources, and the second sideline transmission resource is the two adjacent sideline transmission resources. The time domain position in the line transmission resource is the subsequent side line transmission resource.

Option 3: The configuration information is used to configure multiple sideline transmission resources and one uplink transmission resource for the terminal device. If the time interval between at least one group of two adjacent sideline transmission resources in the multiple sideline transmission resources is less than the first threshold, and/or, the last sideline feedback resource corresponding to the multiple sideline transmission resources is the same as the uplink transmission resource. If the time interval between resources is less than the third threshold, the terminal device deactivates the sideline feedback.

Option 4: The configuration information is used to configure multiple sideline transmission resources and one uplink transmission resource for the terminal device. If there are at least one group of two adjacent sideline transmission resources among the multiple sideline transmission resources that satisfy the above-mentioned first condition, and/or the difference between the last sideline feedback resource corresponding to the multiple sideline transmission resources and the uplink transmission resource If the time interval between them is less than the third threshold, the terminal device deactivates the sideline feedback.

In the fifth option, the configuration information is used to configure one sideline transmission resource and one uplink transmission resource for the terminal device. Sideline transmission resources are resources used to transmit PSSCH. If the time interval between the sidelink feedback resource corresponding to one sidelink transmission resource and the uplink transmission resource is less than the third threshold, the terminal device deactivates the sidelink feedback, and the sidelink feedback resource is a resource for transmitting PSFCH.

Optionally, the first threshold is determined according to the first time interval and the second time interval, wherein the first time interval is determined according to the first sideline transmission resource and the first sideline transmission resource in the two adjacent sideline transmission resources. The time interval of the sidelink feedback resources corresponding to the number of sidelink transmission resources is determined, for example, the first time interval may be the parameter a in the corresponding scheme of FIG. 6 . The first time interval is determined according to the period parameter of the sideline feedback resource configured by the network. The second time interval is determined according to at least one of the following times: the time for the terminal equipment to process the PSFCH, the time for the terminal equipment to prepare to retransmit the PSSCH, and the time for sending and receiving conversion. parameter b.

Optionally, the first threshold is the sum of the first time interval and the second time interval. For example, the first threshold may be a+b in the corresponding solution in FIG. 6 .

Optionally, the first threshold is the sum of the first time interval, the second time interval and the length of time occupied by the PSFCH channel. For example, the first threshold may be the length of time occupied by the a+b+PSFCH channel in the corresponding solution in FIG. 6 . Optionally, the time length occupied by the PSFCH channel is a time length corresponding to one time domain symbol or two time domain symbols.

Optionally, the first threshold is pre-configured, pre-defined by network configuration or protocol, but is not limited thereto.

Optionally, the first threshold is determined by the terminal device. For example, the terminal device determines the position of the corresponding PSFCH according to the time domain position of the lateral transmission resources allocated by the network device, thereby determining the first time interval; further, the terminal device can determine the first time interval according to the second time interval predefined by the protocol. A first threshold is determined, eg, the first threshold is the sum of the first time interval and the second time interval.

Optionally, the time interval between the two transmission resources described in this application may be the time interval between the end position of the first transmission resource and the start position of the second transmission resource in the two transmission resources, for example: the first The time interval is the time interval between the end position of the first sideline transmission resource and the start position of the sideline feedback resource corresponding to the first sideline transmission resource. Of course, the time interval between the two transmission resources may be the time interval between the end position of the first transmission resource and the end position of the second transmission resource among the two transmission resources, or the time interval between the two transmission resources may be this The time interval between the start position of the first transmission resource and the start position of the second transmission resource in the two transmission resources is not limited in this application.

It should be understood that the end position in this application can be described as the end position of the time domain symbol, and the start position is described as the start position of the time domain symbol, for example: the end position of the first sideline transmission resource is the first The end position of the last time-domain symbol of the sideline transmission resource. The start position of the sideline feedback resource corresponding to the first sideline transmission resource is the start position of the first time domain symbol of the sideline feedback resource corresponding to the first sideline transmission resource.

Optionally, the second threshold is pre-configured, pre-defined by network configuration or protocol, but not limited thereto. Wherein, taking the solution shown in FIG. 6 as an example, the second threshold may be parameter b.

Optionally, the second threshold is determined according to at least one of the following times: the time when the terminal device processes the PSFCH, the time when the terminal device prepares to retransmit the PSSCH, and the time when the transmission and reception is switched. That is, the second threshold is related to the capability of the terminal device.

Optionally, the third threshold is pre-configured, pre-defined by network configuration or protocol, but is not limited thereto. Wherein, taking the solution shown in FIG. 6 as an example, the third threshold may be the parameter c.

Optionally, the third threshold is determined according to at least one of the following times: the time when the terminal device processes the PSFCH, the time when the terminal device is ready to report the sideline feedback information to the network through the PUCCH (or PUSCH), that is, the third threshold is the same as the terminal. equipment capacity.

The scheme is illustrated below with an example:

FIG. 8 is a schematic diagram of a resource distribution provided by an embodiment of the present application. As shown in FIG. 8 , for example, according to the configuration of the network device, the PSSCH sent on the time slot 2/3/4/5 is determined, and the corresponding PSFCH is in the time slot 2/3/4/5. For the PSSCH sent on slot 7 and the PSSCH sent on time slot 6/7/8/9, the corresponding PSFCH is sent on time slot 11. Assuming that a time slot includes 14 time domain symbols, namely symbol 0 to symbol 13, if a time slot does not include PSFCH transmission resources, the time domain symbols occupied by PSSCH are symbol 0 to symbol 12, and the last time slot in the time slot The domain symbol (ie, symbol 13) is a guard interval (Guard Period, GP) symbol, on which PSSCH data is not mapped; if a time slot includes PSFCH transmission resources, the time domain symbols occupied by PSSCH are symbol 0 to symbol 9, The time domain symbols occupied by the PSFCH channel are the symbol 11 and the symbol 12, and the symbol 10 and the symbol 13 in the time slot are the GP symbols. It is assumed that the network device allocates 3 PSSCH resources to the terminal device, which are located in time slots 2, 4, and 6 respectively, and assuming that the above-mentioned second time interval, that is, b, is 1 time slot, then b=14 time domain symbols. As shown in the PSSCH of time slot 2 in Figure 8, its corresponding PSFCH is in time slot 7, the first time domain symbol of PSSCH in time slot 2 is symbol 0, the last time domain symbol is symbol 12, and the PSFCH is in time slot 7. The first time-domain symbol is time-domain symbol 11, so the first time interval a=1+4*14+12=69 time-domain symbols. And b = 14 time domain symbols. The time interval between time slot 2 and time slot 4 is two time slots, that is, 28 time domain symbols, 28<69+14, at this time, the terminal should deactivate the sideline feedback. If the terminal wants to activate sideline feedback, the PSSCH sent in time slot 2 can only receive the corresponding sideline feedback in time slot 7. At this time, the PSSCH on time slots 4 and 6 cannot be used. Or, from another perspective, as shown in FIG. 8 , if the terminal device uses time slot 2 to send sideline data and activates sideline feedback, its corresponding PSFCH is located in time slot 7, and the network device allocates it for retransmission. The resources of time slot 4 and time slot 6 are located in time slot 4 and time slot 6, which are earlier than the time of PSFCH. Therefore, the resources of time slot 4 and time slot 6 allocated by the network device cannot be used.

It should be understood that, in the above embodiment, the terminal device determines whether to activate the sideline feedback according to the time interval between multiple transmission resources, which may be that the terminal determines the time between the multiple transmission resources according to the multiple transmission resources allocated by the network. The interval may also be that the terminal determines the time interval according to one or more transmission resources among the multiple transmission resources allocated by the network.

Step S910: The network device sends configuration information to the terminal device, where the configuration information is used to configure multiple transmission resources for the terminal device, and the multiple transmission resources include: multiple sideline transmission resources.

Step S920: The terminal device determines, according to the time interval between the multiple transmission resources, whether to perform lateral transmission on part of the multiple lateral transmission resources.

Optionally, step S920 includes the following optional manners, but is not limited to this:

Optional way 1: if the time interval between at least one group of two adjacent sideline transmission resources in the multiple sideline transmission resources is smaller than the first threshold, the terminal device determines part of the sideline transmission resources in the multiple sideline transmission resources. Sideline transmission is performed on transmission resources.

Optional way 2: if there are at least one group of two adjacent sideline transmission resources in the multiple sideline transmission resources that satisfy the first condition, the terminal device determines that the number of sideline transmission resources in the multiple sideline transmission resources is on a part of the sideline transmission resources. Perform side-by-side transfers. Wherein, for any group of two adjacent sideline transmission resources in at least one group of two adjacent sideline transmission resources, the two adjacent sideline transmission resources satisfying the first condition include: two adjacent sideline transmission resources: The start position of the second sideline transmission resource in the line transmission resources is located before the end position of the sideline feedback resource corresponding to the first sideline transmission resource in the two adjacent sideline transmission resources plus the second threshold . It should be understood that the first sideline transmission resource is the sideline transmission resource whose time domain position is in the front of the two adjacent sideline transmission resources, and the second sideline transmission resource is the two adjacent sideline transmission resources. The time domain position in the line transmission resource is the subsequent side line transmission resource.

In the third option, the multiple transmission resources further include: one uplink transmission resource. If the time interval between at least one group of two adjacent sideline transmission resources in the multiple sideline transmission resources is less than the first threshold, and/or, the last sideline feedback resource corresponding to the multiple sideline transmission resources is the same as the uplink transmission resource. If the time interval between the resources is less than the third threshold, the terminal device determines to perform sideline transmission on some of the sideline transmission resources among the multiple sideline transmission resources.

In the fourth option, the multiple transmission resources further include: one uplink transmission resource. If there are at least one group of two adjacent sideline transmission resources among the multiple sideline transmission resources that satisfy the above-mentioned first condition, and/or the difference between the last sideline feedback resource corresponding to the multiple sideline transmission resources and the uplink transmission resource If the time interval between them is less than the third threshold, the terminal device determines to perform sideline transmission on part of the sideline transmission resources in the multiple sideline transmission resources.

It should be understood that, regarding the concepts involved in the above four optional manners, reference may be made to the explanation of these concepts in Embodiment 1, which will be repeated in this application.

Optionally, the above-mentioned part of the sideline transmission resources is any sideline transmission resource among multiple sideline transmission resources. For example, as shown in FIG. 8 , the part of the sideline transmission resources may be PSSCH resources on time slots 2, 4 or 6.

Optionally, some of the sideline transmission resources are at least two sideline transmission resources in the multiple sideline transmission resources, and the time interval between any two adjacent sideline transmission resources in the at least two sideline transmission resources is greater than or equal to the first threshold, and/or, the time interval between the last sideline feedback resource corresponding to the at least two sideline transmission resources and the uplink transmission resource is greater than or equal to the third threshold. For example: Assuming that the PSSCH sent on time slot 2/3/4/5 is determined according to the configuration of the network device, the corresponding PSFCH is sent on time slot 7, and the PSSCH sent on time slot 6/7/8/9, its corresponding PSFCH is sent on time slot 7. The corresponding PSFCHs are all sent on time slot 11, and the PSSCHs sent on time slots 10/11/12/13 are all sent on time slot 15. Assuming that a time slot includes 14 time domain symbols, namely symbol 0 to symbol 13, if a time slot does not include PSFCH transmission resources, the time domain symbols occupied by PSSCH are symbol 0 to symbol 12, and the last time slot in the time slot The domain symbol (ie, symbol 13) is a GP symbol, and PSSCH data is not mapped on this symbol; if a time slot includes PSFCH transmission resources, the time domain symbols occupied by the PSSCH are symbols 0 to 9, and the time domain symbols occupied by the PSFCH channel are symbols 11 and 12, and symbols 10 and 13 in this slot are GP symbols. It is assumed that the network device allocates 3 PSSCH resources to the terminal device, which are located in time slots 2, 6, and 10, respectively, and assuming that the above-mentioned second time interval, that is, b, is 1 time slot, then b=14 time domain symbols. PSSCH of time slot 2, its corresponding PSFCH is in time slot 7, the first time domain symbol of PSSCH in time slot 2 is symbol 0, the last time domain symbol is symbol 12, and the PSFCH is in the first time domain of time slot 7. The domain symbols are time domain symbols 11, therefore, the first time interval a=1+4*14+12=69 time domain symbols. The time interval between the end position of the PSSCH of the time slot 2 and the start position of the PSSCH of the time slot 10 is 1+7*14=99 time domain symbols, 99>69+14, at this time, the time slot 2 can be and PSSCH on time slot 10 as the above-mentioned partial sideline transmission resources. Or, from another perspective, if the terminal device uses time slot 2 to send sideline data and activates sideline feedback, its corresponding PSFCH is located in time slot 7, and the resource allocated by the network device for retransmission is located in time slot 10 , which is later than the time of the PSFCH. Therefore, the network device can perform data transmission in the resources of time slot 2 and time slot 10.

Optionally, if the terminal device determines to perform lateral transmission on some of the multiple lateral transmission resources, the terminal device activates the lateral feedback.

To sum up, in this application, in the first mode, the terminal device determines whether to perform sideline transmission on part of the sideline transmission resources among the multiple sideline transmission resources according to the time interval between the multiple transmission resources, that is, When the time interval between multiple transmission resources does not meet the time conditions of terminal equipment receiving processing and preparing to send, sideline transmission can be performed on some of the multiple sideline transmission resources, thereby ensuring data normal transmission, thereby improving the reliability of the communication system.
